Nsight Business Voice—PRI Can Boost Your Business’s Efficiency

PRI channels add VoIP technology to your existing phone system.

PRIs, or Primary Rate Interface, have 24 channels (23 “B” channels and 1 “D” channel) that are capable of transmitting up to 1.544 Mbps. It’s designed for uses such as PBXs, computer telephony, and voice processing systems. ‘D’ channel signaling provides a powerful and flexible mechanism for call control, network management, security, and other applications.

A single number or a block of numbers (DID-Direct Inward Dialing) can be assigned to the PRI. These numbers are not associated with any specific channel and can be used to dial directly to an extension.
